An approximate string matching library for the Go programming language.

Data used in record linkage can often be of dubious quality. Typographical errors or changing data elements (to name a few things) make establishing similarity between two sets of data difficult. Rather than use exact string comparison in such situations, it is vital to have a means to identify how similar two strings are. Similarity functions can cater to certain data sets in order to make better matching decisions. The matchr library provides several of these similarity functions.
